1. INTRODUCTION

An area of 1450 sq km falling in parts of Goalpara (250 sq. km), Kamrup (1030 sq km) and Barpeta (170 sq km) districts of Assam was covered as per the Annual Action Plan 2012-13 and 2013-14 of Central Ground Water Board, North Eastern Region, Guwahati.

The study area spread over 1450 sq.km falling under Survey of India toposheets no. 78 J/16, 78 N/4, 8 and 12 lies between North latitudes 26º00/00// & 26º15/00// and East longitudes 90º45/00// & 91º45/00//. The study area lies mostly in the southern part of the Brahmaputra River.

The total population of the Kamrup district is as per 2011 Census is 12,60,419, with 6,55,630 Male and 6,04,789 female. The total population of the Goalpara district as per 2011 census is 10,08959, with 514,162 male and 49,4797 female. The total population of the Barpeta district as per 2011 Census is 16,93,190 with male 8,67,891 and female 8,25,299. The population density as per 2011 Census is 553.

The study area is characterized by an almost flat plain except for few low hills that break the monotony of the terrain. The Study area represents association of variety geological formations ranging in age from Archaean to Recent. The assemblages of different formations play important role in controlling occurrence, distribution and movement of ground water. The study area is underlain by the Archaean Gneissic complex (inselbergs) and Quaternary Alluvial formations. The Archaean gneissic complex includes of metamorphic complex of gneiss, schist, phyllite intruded by acid/basic intrusive.

2. MAJOR GROUNDWATER ISSUES IN THE AREA

Major groundwater related issues found in the study area are low stage of development, shallow groundwater level, meager irrigational infrastructure and in major parts of the study area higher concentration of iron in groundwater. In 85% of net sown area no irrigation facility is available. An agrarian society where majority of farmers are categorized as marginal and small. Average land holding of marginal farmers is 0.4 ha. Power supply is irregular and in places non-existent.

3. MANIFESTATION AND REASONS OF ISSUES

In the study area depth to water level ranges from 0.50 to 4.64 m bgl during post-monsoon and water level ranges from 1.00 to 7.85 m bgl during pre-monsoon. In major part of the study area seasonal fluctuation varies from 0.22 m at Maligaon to 4.12 m at Azara. The details of key wells have given in table no-10.

The climate in the study area is moderate during the winter and it is hot during summer. Rain makes first appearance in the month of April. Monsoon rain normally started from the Month of June and heavy rain occurs during September. The average annual rainfall in the area varies from 1500 to 1800 mm. The average relative humidity in a year is 78.7 per cent.

Infrastructure for irrigation in the study area is very meager. Out of the total net sown area of 74755 ha only 15% has been brought under irrigation till date. SI District (p) Study Net Area Land under Land which No. area Sown Irrigation (in can be brought (in Ha) (in Ha) Ha) under Irrigation (in Ha) 1 Kamrup 103000 54918 10837 44081 2 Goalpara 25000 11540 80 11460 3 Barpeta 17000 8297 392 7905 Total 145000 74755 11309 63446

To know the water quality of the study area, water sampling done from both shallow and deeper aquifers. Ground water quality of both shallow and deeper zones were discussed below. 10 nos. of water samples from deep tube wells and 47 nos. of water samples from dug wells were collected during the study for the chemical analysis. Water samples collected during the study were analyzed for the different chemical constituents at the Regional chemical laboratory of CGWB, NER Guwahati and result are as given in table-12 format.

The pH of the Ground water varies from 7 to 9 indicating slightly basic character of the water. The value of EC varies from 1406 to 114 µs/cm at 250 C. The fluoride content of water samples are varies from 0.13 to 1.52 mg/l. The iron content of dug well water samples varies from 0.17 to 11.47 mg/l and from 0.37 to 5.82 mg/ lit for deep tube well sample. Location of higher concentration of iron in groundwater is depicted in Map-8. Summary of results of chemical analysis data showing concentration of iron in groundwater is shown in table below.

Table: Summary of chemical analysis data showing concentration of iron in groundwater Result of Water samples from dug wells Result of Water samples from deep tube wells

It can be seen from the above table that 64% water samples collected from dug wells are having iron content more than the desirable limit i.e., 0.30 mg/ lit (set by BIS). And 100% water samples collected from deep tube wells are having iron content more than the desirable limit.

The study area is characterized by an almost flat plain except for few low hills that break the monotony of the terrain. The northern most part of toposheet No.78J/16 which falls mostly in Barpeta district is flood prone area. A significance of SE part of the study area is the large number of sandy river islands in the Brahmaputra river. The alluvial land is flat with gentle slope of less than 1m/ km towards Brahmaputra River. The hills mostly are isolated inselbergs with heights ranging between 60 m to 269 m above msl.

The mightily Brahmaputra flows from East to West in the study area and the main tributaries of the Brahmaputra are Kulsi ,Krishnai, and Hajo satu nadi. Dudhnai and Krishnai river originate from hills of Meghalaya then join each other on the western part of study area and flow as river of Mornoi up to its confluence with the Brahmputra and ultimately join near south Salmara of Dhubri District. All the rivers are perennial in nature. The common drainage patterns are sub-parallel to parallel and dendritic. Apart from the Brahmaputra river, up to third order streams are found in the study area.

4. AQUIFER GEOMETRY AND CHARACTERIZATION

The main objective of the study is to delineate the horizontal and vertical disposition of aquifer as well as to study the aquifer character. In this connection 69 key wells including existing CGWB monitoring stations (Dug well) were monitored in different season. Locations of the monitoring stations were shown in Map No-14. To know the aquifer disposition in the study area, exploratory wells data, VES data available with CGWB and some data of state departments, Govt. of Assam were utilized.

CGWB has drilled 16 EWs within a depth range of 94 to 220 m. A thin layer of discontinuous clay beds occur at surface all over the alluvial deposit ranging in thickness from 5 to 10 m. The tube wells drilled in alluvial deposits show alternate thick beds of sand, gravel and thin beds of clay.

It can be deciphered from the lithologs of different exploratory wells drilled by CGWB that EW show that in regional scale mono aquifer system occur in the area. The aquifer is comprised mainly of medium to coarse sand. This sandy aquifer is having gravel and clay intercalations in places. In some places due to the presence of clay intercalations 2 to 4 granular zones occur in the study area. Separations of two or more granular zones by clay beds often misguide to classify the aquifers into a multiple aquifer system. However, these clay beds are mostly in lensoid shape and they pinches out within a short distance. Thickness of the saturated zone varies from 50 to 100 m within a depth range of 160m. The isopach map of this aquifer shows that isopach value increases towards north of the study area i.e., towards the Brahmaputra flood plain. The deep tube wells constructed by CGWB show yield of 33 to 46 m3/hr for a drawdown of 2.46 to 7.46 m (maximum drawdown observed near inselbergs).

Mono Up to 160 35 – 55 2 – 7 10 -12 hr 8878 – 4.2 x 10-6 to aquifer 14500 1.7 X 10-3

Groundwater occurs under unconfined condition in the topmost part of the system. Unconfined condition extends down to the depth of 15 m. In the deeper parts of the system groundwater occurs under semi-confined to confined conditions.

According to the results of interpretation of VES curves, correlation of the data with hydrogeological details of exploratory boreholes and taking into account the apparent resistivity following conclusions have been drawn in respects of parts of Kamrup dist. 1. The top soil with resistivity in the range of 100 and 270 Ohm with thickness within 10m comprises top soil with clays / hard clays etc. 2. The underlying layers below the top soil in the depth below the top soil layer with varying resistivity within 100 Ohm m in general is indicative of sandy formation intercalated with clays / hard clays etc. Comparatively high resistivity above 100 Ohm m is indicative of the hard clay/semi-consolidated or consolidated formation. 3. The inferences for bottom portion are drawn on the basis of interpreted results of surface resistivity surveys, apparent resistivity pertaining to extreme portion of VES curves and hydrogeological data. The VES locations are shown in Map No-05.During the survey H, HK, HA type VES curves were obtained. The inferences drawn on the basis of interpreted results could not be obtained for deeper formation due to the limitations of unavailability of large and straight stretch for current electrode separation. Interpreted results of VES and inferences with respect to possible sub-surface geology are given in Table.

As per the report on dynamic groundwater resources of Assam, 2011 the study area is having a net groundwater availability of 545 mcm, gross annual draft of 130 mcm and stage of development is 24%.

MANAGEMENT STRATEGIES

The study area is having meager irrigation facility. A vast land of 63446 ha does not have any irrigation facility which can be brought under irrigation using the huge dynamic groundwater resources available in the area. It is proposed to bring 60% of area under paddy and 40% under non-paddy cultivation. Water requirement for paddy cultivation would be 457 mcm while that for non-paddy cultivation would be 76 mcm. Total water requirement to bring this entire uncovered area under irrigation is 533 mcm. As per the report on dynamic groundwater resources of Assam, 2011 the study area is having a balance groundwater availability for future uses in the order of 397 mcm. If a plan is made to develop 60% of the balance dynamic groundwater resources available (238 mcm) in the area for the irrigation purposes then 7945 nos. of tube wells (considering a unit draft of 3 ham/yr) can be constructed in the area. CGWB has established that aquifer in the area is a prolific one and this can be sustainably developed to irrigate this vast land. A tube well yielding 40 m3/hr, runs for 12hrs/day for 200 days will create a draft of 9.6 ham. To meet the water requirement of 533 mcm, 5552 nos. of such tube well will be required (considering a unit draft of 9.6 ham/yr). Extraction of 295 mcm more water from the aquifer will lower water level by 1 m which will be easily replenished during monsoon (Avg annual rainfall 2m). Tube wells can be designed in the study area within a depth of 50 m, tube wells can be constructed by tapping 20 m of granular zone is expected to yield 40 m3/hr for a drawdown of 4 m. Wells may be constructed by using 6// dia casing pipe down to 20m, 6// dia 1 to 1.5 mm slot pipes for 20m and 6// dia 10 m blank pipe. Though huge GW resource is available but farmers in the area are poor and it may not be possible for them to construct tube wells individually. Community based irrigation schemes through groundwater may be taken up by Govt., which will greatly boost the socio- economic conditions in the area. In view of the grim power situation in the area, and – SOLAR PV Pumps would not be able to deliver the requisite water, diesel pumps are the best available option inspite of high running cost.

Cost Estimates One time expenditure to construct 5552 tube wells @ Rs. 2,00,000/= is Rs. 111 crores and cost of 5 HP diesel pumps, yearly running cost and maintenance @ Rs. 91,300/= is Rs. 51 crores.

MANAGEMENT PLAN By providing irrigation facilities to 38000 ha of paddy land 110,000 metric tons of food grains (@ 2900 kg/ha) can be produced. This will boost the economy by providing Rs. 199 crores per annum income (Recent minimum price of common paddy Rs. 1800/Qn). Further by providing irrigation facilities to 25000 ha of non-paddy land 15,000 metric tons of non-paddy can be produced. This will generate an income of Rs. 8 to 46 crores per annum (recent minimum price of vegetables Rs. 520/Qn to Rs. 3000/ Qn of oilseeds). Total one time expenditure Rs. 162 crores. Benefit Rs. 207 to 245 crores per annum. Groundwater in the area is infested with iron, therefore before consumption aeration/ filtering/ installation of Iron Removal Plant is necessary. At present PHED, Assam is supplying treated drinking water in the area. Apart from this, individual houses are using sand filter to remove iron. Farmer’s co-operative societies may be formed which will look after maintenances of the tube wells. Map No- 1
